The working principle is as follows:
when the device works, when the network wire is installed, a main wire is extended in through the wire inlet 3, then a branched wire is extended out through the wire outlet 2, the door panel 4 is opened after the installation is finished, after the internal wire is connected well through the wire pulling mechanism 31, the main wire and the branched wire are moved and contracted, so that the bending of the internal wire can be avoided, meanwhile, when the wire is straightened, the internal flat cable looks more orderly, after the electrified wire is straightened, the magnetic field generated by bending is avoided, the optical fiber is straightened, the influence on the network can be avoided, the use quality of the network wire is improved from multiple aspects, the practicability of the device is improved, the main wire is connected to the upper end of the main connector 7, the branched wire is connected to the upper end of the branched wire dividing head 8, after all the wires are connected, the knob 12 is rotated through a tool, the knob 12 is rotated to drive the first bidirectional threaded rod 10 to rotate, when the first bidirectional threaded rod 10 rotates, the two first sliding blocks 9 move to opposite sides in the first sliding groove 11, the first sliding blocks 9 drive the upper connecting body 5 and the lower connecting body 6 to contract, the lower connecting body 6 drives the second sliding block 15 to move in the second sliding groove 14 when moving upwards, and because the second sliding block 15 is electrically connected with the first conducting sheet 13, when the upper connecting body 5 and the lower connecting body 6 move upwards and downwards, because the second sliding block 15 is in a contact state with the first conducting sheet 13, the open circuit phenomenon can not occur during moving, so that after the circuits are connected, the circuits can be contracted, a plurality of circuits can be straightened and compacted, the bending phenomenon of the circuits can be avoided, the practicability of the device is improved, when required, the number of main lines required to be separated is different, and according to the construction requirements, at this time, the U-shaped latch 19 is pushed, the U-shaped latch 19 moves in the cavity 33 and pulls the first spring 20, the tap 8 moves in the third sliding groove 18, when the U-shaped latch 19 moves to a proper position, the U-shaped latch 19 is released, the U-shaped latch 19 is reset by the first spring 20, so that the tap 8 is fixed, because the tap 8 is electrically connected with the second conductive sheet 17, so that the disconnection does not occur at the time of tapping, the area of which main line the tap 8 is located can be easily distinguished through the dividing line 30 fixedly connected to the upper surface of the upper connector 5, and by moving the tap 8, the connection position can be autonomously adjusted as required, and the space inside can be reasonably used, because the connected lines are not in excess length each time during construction, so that when the contraction of the upper connector 5 and the lower connector 6 is performed, the short wire will affect the long contraction, at this time, when some longer wires are still contracting, the short wire will pull the lower connecting body 6 moving upwards relatively by the main joint 7 to move downwards, at this time, the main joint 7 drives the third sliding block 22 to move downwards in the fourth sliding chute 21, at this time, the third sliding block 22 compresses the second spring 23, so that each wire can be stretched when the upper connecting body 5 and the lower connecting body 6 contract, the practicability of the device is further improved, when the first bidirectional threaded rod 10 rotates, the first bevel gear 34 rotates, the second bevel gear 32 rotates, the first threaded rod 24 rotates to separate from the left baffle 25, at this time, under the action of the third spring 28, the fourth sliding block 29 moves in the fifth sliding chute 26 to drive the baffle 25 to move, it is specifically noted that when the first threaded rod 24 and the left side baffle 25 are not disengaged, the two fourth sliders 29 restrict the fourth slider 29 at the rear end of the right side under the action of the second bidirectional threaded rod 27, so that the wire inlet 3 can be blocked after the installation is finished, and the main wire can be pressed to a certain extent, so that the inner wire is more straight and more stable.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
